Profiler 4: Criminal Investigation Team

Ji Miao smiled and said, "Will Team Jiao accept my interview in person today?"

Jiao Yang heard that she came and went "in person", and said with a smile; "Okay, Teacher Ji, let's stop bragging about business. We are in the front line, and it is not convenient to often appear on camera, so we should call a clerical colleague to come." Come on, Ke Luoluo, come here."

"what?"

Ke Luoluo was a little puzzled when he heard that, "Jiao Dui, I'm an intern, how do I know what to say?!"

Ji Miao was taken aback, not very happy in her heart, she still smiled and said, "Well, let Jiao team come."

Ke Luoluo saw that the beautiful hostess was obviously unhappy, so she deliberately stepped forward and said, "Then Jiao Jiao, let me try, if it doesn't work, let this young lady cut me off!"

The parents of the victim three years ago were both working out of town. After the death of their daughter, they seldom went home. Later, even the deceased’s grandparents were picked up.They originally wanted to rent out the house, but the case was quite big back then, not to mention this town, even the nearby towns knew that the house had died, so they couldn't even rent it out, let alone sell it.

Fortunately, this is the case, so the scene was preserved as much as possible.

The victim's parents were still very young, in their 40s, when Jiao Yang was about to step forward, a young man in his twenties walked over and said, "Uncle.

The victim's father looked tired and complicated, and only waved at the young man, "Didi! Are you in college?"

The young man smiled and said, "Junior, I'm about to graduate."

Jiao Yang couldn't help but glanced at the young man, "Are you also the victim's family?"

The young man shook his head and said, "No, it's a neighbor."

Jiao Yang nodded and said, "What's your name?"

The young man froze for a moment, then said hesitantly, "My name is...Meng Di."

At this time, Hou Xiyong, Yu Xiaoguang and others had already begun to conduct inspections indoors.

Jiao Yang asked Ke Luoluo to invite the victim's father aside and asked about the situation back then, but because the couple had been working in other places, they knew very little about their daughter, and they couldn't say anything useful now. information.

Jiao Yang read the transcripts from that year, and it was almost the same as before, so he walked into the farmyard.

Apart from Hou Xiyong, Fang He and the others, the two trace inspectors are also busy.Outside the courtyard wall, there are crowds watching the excitement.Jiao Yang unconsciously stood in a blind spot, looking at the crowd from the corner of his eye.

Psychologically, most murderers return to where they came from, and hopefully this time too.

Jiao Yang had seen the photos of the scene many times, and walked in according to the picture.He came to the room of the deceased, closed his eyes unconsciously, and imagined the position of the deceased according to the data.The thin and slender girl was hanging from the beam, and the long golden skirt reached her ankles... That kind of large old-fashioned copper lock is used to lock the iron gate of the yard outside?Gold dust all over the floor...

However, there is no such thing as gold powder in ordinary families, right?If it is silver powder, it may also be used for painting water pipes and other things.

Silver powder is aluminum powder, and the so-called gold powder is actually an alloy of metal copper and zinc.Both are very versatile.

After a very detailed on-site investigation, no useful clues were obtained.

This was expected, Jiao Yang was about to take the team back, Ji Miao greeted him and said: "Jiao team, I will go back and ask my colleagues to edit the sample and send it to you."

Jiao Yang smiled and said, "Okay, please trouble Teacher Ji."

Ji Miao laughed and said, "I don't have a teacher's certificate, why do you keep calling me that? You call me old!"

Jiao Yang paused slightly, "Oh..."

Ji Miao observed his words and immediately said, "You're just kidding, just call me Miaomiao!"

This title was a bit ambiguous, before Jiao Yang could figure out how to answer it, Ke Luoluo stepped forward and said, "Teacher Miaomiao, thank you so much today!"

Ji Miao glanced at Ke Luoluo, smiled and left without saying anything.

When they got into the police car, Ke Luoluo curled his lips and said, "They're all foxes of a thousand years old, who are they chatting with!"

Jiao Yang shook his head involuntarily, "What are you talking about? He is here to help us today, please be polite."

"Helping is of course helping."

Ke Luoluo grabbed his sportswear casually, and said with a smile: "But people, it's not us who helped, but you! Didn't you see how people looked down on me just now, and kept stretching your neck to look at you... ..."

"This is……"

As soon as Jiao Yang lowered his head, he saw Ke Luoluo unconsciously picking at the pattern of the sports jacket with his fingers, and the golden pattern was scratched by her a few lines, which appeared somewhat blurred.

"do not move!"

Jiao Yang clasped Ke Luoluo's wrist, raised her wrist, and looked down at the hem of her sports jacket carefully.

Ke Luoluo was caught off guard and was startled, "Jiao Dui, what are you doing..."

"Feel sorry!"

Jiao Yang hastily let go of Ke Luoluo, and said thoughtfully: "Maybe there really is a blind spot that has been overlooked."

Seeing Jiao Yang staring at his clothes, Ke Luoluo was a little embarrassed.She subconsciously twisted her clothes again, "Head, what's wrong with my clothes?"

Jiao Yang raised his head slightly, "Will the pattern on your dress fade?"

It turned out to be about this...Ke Luoluo thought that Jiao Yang must have thought that she was sloppy when she saw that the patterns on her clothes were all overwhelmed, or that the clothes she wore were cheap, so she stammered and explained: "Yes, It's my nails, if I accidentally scratched him, it might have been scratched..."

"nail!"

Jiao Yang put his hands together and said, "Since the nails can scratch the patterns, can they be peeled off in one piece?"

Ke Luoluo saw that he was very serious, and he didn't look like it was just because he didn't wear a piece of clothing, so he said suspiciously: "It should be okay, just like nail polish that can be peeled off?"

Jiao Yang excitedly said: "Okay, then what fell on the ground at the scene may not be the gold powder, but the fabric on that dress!"

Jiao Yang returned to the office in a hurry, and immediately took the file of this case to read.

However, the dossier of that year did not show the detailed composition of the gold powder.

Jiao Yang directly asked Ke Luoluo to go to the physical evidence room, and brought out several things that were on the deceased's body before his death.

Jiao Yang put on the thinnest disposable gloves, first touched the feel of the dress through the plastic bag, and then looked at the scattered powder in the plastic bag to the light for a long time.

According to his naked eyes, the texture is the same.However, this cannot be based on feeling alone.Jiao Yang asked Ke Luoluo to go through the formalities and send the two pieces of evidence to the Technical Investigation Detachment for testing.

The Technical Investigation Detachment worked overtime to make comparisons, which proved that the powder left in the ground was indeed the same composition as the coating on the upper surface of the skirt, and it was a kind of 200-mesh gold powder in jargon.

Jiao Yang breathed a sigh of relief, and called the team members to discuss the case.

Jiao Yang put a few pieces of evidence on the table in the meeting room and said: "In the past three years, even if we got fingerprints and footprints at the scene, they are already contaminated physical evidence, and it is difficult to go to court. Going to the scene and calling the media over is just to attract the suspect's attention. Comrades, we have to rely on these confirmed evidence to solve the case!"

Hou Xiyong said: "Boss, if you can solve the case with these things, can they still close the case as an accident?"

Jiao Yang said: "Three years have passed, and the difficulty has indeed become greater, but after all, criminal investigation technology has also improved. We mainly dig out to see if there are any blind spots that were not discovered back then."

Hou Xiyong said: "But boss, this case has dragged on for a long time. The colleagues who handled the case must have checked it many times. We didn't find any new evidence this time. What blind spots can there be?"

"I know!"

Ke Luoluo proudly raised his hand and said, "That's the so-called gold powder left at the scene. It's not gold powder at all, but the gold powder that fell from the suspender dress worn by the deceased!"

Fang He said: "I used to look like it too, but what's the use of it?"

Jiao Yang said: "I accidentally discovered that the golden patterns on the textiles were either dyed or printed with gold powder. I asked our technicians to test the gold powder left over from the scene and found that it was a kind of gold powder. The copper powder is 200 mesh, the price is relatively low, and it is suitable for gold printing and textile printing. It is indeed the same material as the gold attachment on the nightdress worn by the deceased.

The use of gold powder with this composition shows that the material of the skirt worn by the deceased is relatively poor, and the gold color on it is easy to fall off.On the hem of the nightdress, there were irregular scratches and scratches.The deceased's hands and feet were bound, and it is unlikely that he would have made such marks himself.

So I speculate that at the scene of these cases three years ago, there was indeed a second person besides the deceased.When the two played these games, the deceased showed a reaction of suffocation and struggle.The other person panicked when he saw this scene, and hurriedly tried to rescue the dead.

He lifted the deceased's calf, ankle and other parts, trying to put the deceased down, but because the rope around the deceased's neck was tied too tightly, he failed, and the deceased passed away.But in the process, because of his haste and force, he grabbed some of the woven gold from the hem of the deceased's skirt and scattered it on the ground. "

There was a burst of discussion in the meeting room immediately.

"Then, is such a case deduction an accident or a murder?!"

Jiao Yang said: "Whether it's an accident or a murder, we have to find this person to find out."

Hou Xiyong said: "Doesn't that mean we went back again? There are no traces at the scene, how can we find it?!"
